It is an object of the vinvention 'to provide a Casement window operator which is arranged to 'pass through a screen and to swing the window open and closed by direct thrust and pull.

It is a further and more particular object of the invention to provide a window operating .rod which is composed of telescoping'sections so arranged that the eiective length of the operating rod can be quickly and conveniently shortened or lengthened and set.

It is a further important object of the inven-v tion to provide an operating rod of the kind referred to which can be collapsed to its minimum length and then turned in,'paral1el to the plane of the closed sash, so as to be held completely out of the way. 1 Other objects have to do with thelocking of the operating rod in various operative positions, and with provision for sealing the opening in the screen frame `through which the rod passes, against vthe admission of insects, While having the screen free to be removed. s

Other objects and advantages will hereinafter appear.

In the'form of the invention illustrated in Figs. 1 to 7, inclusive, a easement window sash Iv is shown as hingedly mounted upon a frame 2V by means of a hinge 3, the hinge being desirably of the form disclosed in Letters- Patent of the -UnitedStates No. 1,987,516 granted to Edmund Peremi and Louis Toth on January 8, 1935. Since the construction of this hinge is fully disclosed in the patent referred to a detailed description of i thehinge is not thought necessary. It is characteristic of the hinge, however, that as the window sash is swung open the edge of the sash supported by the hinge is carried inward across the window opening so that when in fully opened position the sash stands at right angles to its original position and in a plane located substantially inward (about one-fourth of the width of the window) from the jamb engaged by the hinged edge of the sash when the sash is in closedposition.

A screen 4 is provided at the inner side of the Window frame, and a bracket 5 attached to the sash has an arm 6 which extends inward through an opening 1 in the screen frame. 'The arm 6 extends also througha closing plate 8which is mounted on the screen frame at the inner-side thereof, and into a cylindrical socket member 9. The socket 9 is secured by a pivot bolt In to a. base-bracket Il. The base bracket Il is best shown in Fig. 6. It includes ears I2 provided with screw openings I3 for attaching it to the sill,

and a raised central portion which engages the edge of the screen and covers the mouth of the opening 1 in the screen frame.

'Ihe inner end oi' the arm 6 is pivotally mounted between ears I4 oi a block I5. The block I5 is' fixed to the end of a. tubular rod I6, which rod is telesc'opically received within a rod I1.

and I1, and with the means whereby the two rods may be conveniently adjusted longitudinally with respect to oneanother and locked in various adjusted positions. Y

The rod I1 has an operating knob or nger piece I8 aflixed to its end by means of a cross pin I9. A solid rod 20 extends into a socket in the nger' piece or knob I8 and is held in xed relation to the knob by the cross pin I9. The rod 20 has a reduced inner end 2I which is threaded into a nut 22. A sleeve 23 surrounds the rod 2] between a shoulder 24 of the rod and the nut 22. As best seen in Figui the sleeve 23 has slots 25 formed in its end toward the nut so that the end of the sleeve which faces the nut may be expanded by drawing the nut into the sleeve. 'Ihe nut 22 has a .conical face which ilts against complementary faceportions 28 at the ends of the segme ts into which the sleeve 23 is divided by the slots 25. The nut 22 is held against rotation by means of a slot formed in the side oi the nut, which slot embraces a key or rib 21 on the interior oi the tubular rod I8. It is' oi no importance whether the-sleeve 23 turns with the rod 28 or not, but it is important that the sleeve substantially ll the tubular rod I6 so that when its -end segmentsA are -expanded slightly they will be clamped against the inner face of the rod I6.

The sleeve 23 is accordingly provided `with a slot 28 to accommodate the key 21 of the tubular rod I6. A limiting nut 29 is provided upon the .end of the threaded portion of the rod 20 to prevent the rod from being completely unscrewed from the nut 22, and also to avoid useless turning of the knob.

With the parts arranged as shown and described it is necessary only to turn the knob I8 through a fraction oi.' a revolution to clamp or umnamp the sleeve 23 m the tubmar maA Is.'

The sleeve is clamped by turning the knob I8 clockwise to draw the nut 22 into the recessed end of the` sleeve, and is unclamped by turning the knob I8 in the opposite direction to back the nut .22 oil a little.

When the operating rod formed jointly bythe tubular rods I8 and I1 is to be lengthened-or shortened the sleeve 23 is unclamped and the knob I8 is moved longitudinally. The new adbeing attached to the sill. In this position the rod occupies little space and is completely out of the way. It also serves as a reasonably effective window lock for ordlnary'purposes although it is not intended to be exclusively relied upon ior locking a window closed.

When'it isdesired to open the window, the rod is pulledfree of the hook 38, swung around sul)-- stantially into line with the arm 6, extended to its full length or any lesserlength desired, fixed at the extended length and thrust outward.

. Provision ismade for lockingthe rod in any adjusted position desired so that the window -maybe retained firmly in `any ldesired position. 'It has already been'made clear that the arm 6 and the operatingrod pass through a socket 9 which is,l rotatably mounted upon a base I I. The socket 9 has a wide slot 3l formed in its cylindrical wall at the inner side anda smaller opening-or passage 32 just large enough to accommodate the rod I1 formed in the opposite side of the cylindricall wall. A cylindricalclamping block or plug 33 lts in the socket and is similarly provided with wide and narrow openings 34 and 35 which are connected by a'passage .through the plug for receiving the operating rod.

rotation thereof. Within the socket and between the ears 39, the .cap is provided with clamping surfaces 40. A wing nut Il is threaded onto the the rod for further adjustment. The spring 31A l urges the cap and plug apartat all times.

Whenever the window is open either part-way 'or completely, a portion ofthe rod extends through the opening 32 of the socket 9.` The' outer rod` I1 substantially fits the opening while the innerrod I6 is so near in size to the size of the opening that insects cannot pass through the socket: The bearing block 8 carried by. the screen frame engages the outer surface of the socket 9 and thus precludes the possibility of an Y insect too large to pass through the .screen mesh gaining ingress to the building.

'Ihe block 8 is not, however, attached tothe socket but can be lifted ofi the socket with the screen when it becomes necessary to remove the screen in order to permit the window to be cleaned. The passages through the block and throughthe screen frame are open at thebottom to permit removal of the screen.

In .the form of the invention dis'closed in Figs. 8 to A12. inclusive, the sash Ia, frame 2a, and hinge 3a may be the same as in the form of Figs. 1 to '1. The screen la is of modied'construction for cooperating with a modiiied form of rod clamp. lThe operating rod and the rod clamp are also dierent trom the corresponding members of Figs. 1 to '1. Y

The operating rod 5891s hingedly connected to an arm 5I which extends inwardirom 4the sash Ia and comprises an outer tube 52 and an inner tube 53.' The walls of the inner tube are brought together in parallel relation and,- together with an interposed spacer S4, form a hinge ear; A rivet 55 .passed through the arm 5I and through the ear Vconstitutes the' Divot lbearing for the lhinge. The outertube 52 has `la iinger piece or knob secured to'itjat one end, and this knob carries a rod I1 which extends within the tubes 75 envases I and ywhich carries at its end remote from the knob, a block 88. The block 58 is mounted upon "a reduced portion 59 of the rod 51 against-'a shoulder, and is xed upon the rod by upsetting or spreading the end, oi' the reduced portion oi` the rod. The block 58 comprises a base portion 60 which engages the inner wall oi the tube 53 and serves as a guide. The block also com' that they may be expanded around the head 6l oi the block 58 and caused to embrace the neck portion 62 of the block. The ilngers-SS are fairly stii so that when they thus engage the neck portion of the block 58 they hold thel rod 50 fully extended to its maximum length with considerable force and thus enable the rod to be used to thrust the window open and to secure the window in any desired position. When it is desired to collapse the rod 8B; however, this may be readily done by strildng the knob 5G a sharp blow with the palm of the hand. When this is done the inertia of the window sash offers sumcient resistance to cause the head (il -to spring past and free of the fingers $5.

The rod 5|! is adapted 'to be operated through a clamping device 66 mounted on vthe window'sill. This device comprises a supporting bracket $1 'which is secured by screws 68 to the sill. The

bracket 61 includes a horizontal web for engaging the edge of the screen and a vertical Aweb which extends upward closely adjacent the screen frame and which has an opening 6.9i formed through it in line with a passage 18 through the edge of the screen frame. 'I'he bracket 68' fini cludes an ear-1i through which a wing screw described again.

12 is threaded. A reduced end portion 13 of the screw 12 is passed through an e'ar 14 of a clamping member iE and upset. The clamping'member 15 has a slot 16a formed in it through which the rod 56 operates.' A covering guide plate 16 is secured tothe bracket 66 and forms a cover. and'guide for thev clamping member 15. The screw 12 is rotatable relative to the clamping member 15 but compels the clamping member to move longitudinally in unison with the screw.

The rod Sli is clamped by operating the screw to force the clampingmember 15 toward the left as seenin Fig. 8 and is unclamped by turning the screw in th'e opposite direction.

The operation is generally similar to the op- 13 to i6 the sash Ib, theY trame 2b, and the hinge.

3b may be the same as in the forms already described. The screen db is like the screen da of Figs. 8 to l0 and the rod clamping device is-the.

same as that of Figs. 8 to 10, and l2. Corresponding reference numerals have been applied .to the rod clamping device with the ,subscript b added in each instance. AThese parts wiilnot be 'Ihe operating rod, however, is oi.' a diiierent construction from the operating rods 'already described. An arm lSib fixed to the sash extends inward and is pivotally connected to an. end oi' a tubular rod 11, the rod 11 being iiattened at its end and having a spacer 18h' between its at end walls. The rod 11 at its end remote from the arm iibfcarries across pin 1a which. extends through the walls ofthe rod and projects beyond the walls for a short distance. A second rod section 19 is yarranged. to telescope upon the rod 11. This rod comprises an end cap having an yoperating ring 8| formedupon it and outer and inner sleeves or tubes 82 and 83. Both sleeves pin 84a. 'I'he outer sleeve 821s unbroken and snugly tits the inner sleeve 83. rThe inner sleeve 83, however, is provided at diametrlcally opposite points with longitudinal slots 8l, and each of these slots is provided with correspondingly located -bayonet slot branches at several points, the

branch slots being indicated at 85, 88 and 81 in Fig. 14. The ends of the. pin Ware received in the slots of the tube B8. The illustrated ar- 'rangement gives a choice oi three operating lengths for the rod, namely, the minimum length which is secured when the pin 18 occupies the are made fast to the cap B0 by means of a cross from the bayonet slots the rod section 19 is rotated clockwise so as to carry the main slot 84- into engagement with the pin. 'The rod secr tion 19 may now be thrust longitudinally rela#- tive to the rod section 11. It it is desired to arrest the pin 18 at the slot Bt and locate it in the slot, a slight counter-clockwise pressure may be maintained on the handle di of the rod section 19 as the section 18-.ls thrust longitudinally. Ii itis desired to shift the pin 18 into the slots 81, however, the rod section -19 may be thrust longitudinally without applying any torque or with a slight clockwise pressure applied until the slot tures. We do not, therefore, desire tolimit our.

selves to the speciiic constructions illustratefrl,l but intendv to cover our invention broadly in whatever form its principles may be utilized.
